I had my X5 in for an oil change today, and the SA told me that the mechanical pump on the 35D normally fails in the range of 110k KM - 130k KM (currently have 119k KM). I know the electrical pump normally fails around 70k -80 k miles, but has anyone had the mechanical pump fail on their 35D?
If yes, at approximately what mileage? I'd rather change the pump and thermostat than have a failure on the way to our cottage (summer home) 1.5 hours away in rural Ontario. Of course I'll do the work myself and take some pictures
